Hello Florida, Hi DE ! Yes, I am from Europe - I live in London ! We do call them "Eiderdowns" here, I am so glad you remember them twixbar! And interesting that perhaps they just don't exist in America? It is true that they are a traditional thing to have on a bed. It would be great if I could figure out how...
I have some links here from eBay, to show you the kind of thing!

Although, none of these are the same as the one I have, as the one I have also has patches of fabric in a decorative design. You woudn't use it as a quilt directly, as it is more like a decorative blanket. I use mine at the bottom of my bed to keep my toes warm ! Interesting that this might just be a European phenomenon! Let me know if anyone knows differently though!
